Men’s ergonomic thermal T-shirt, first layer, long sleeve, made with merino wool, a natural fibre that helps retain body heat and offers characteristic softness. Recommended for sports at very low temperatures. Made without seams around the edges and with flat seams at the sleeve junction for greater adaptability and a high level of comfort. At the elbow, there is an anti-slip strip so that the T-shirt does not wrinkle while you are wearing it. Made with thermowool performance technology, which aims to guarantee the athlete maximum comfort so they can face every sporting challenge at full performance, ensuring maximum freedom of movement. It also has UPF 50+ sun protection factor, thanks to the type of weaving and the raw materials used in the manufacturing process. In addition, as with the base for all our garments, it is combined with Lurbel’s Silver Base Layer mesh, with high antibacterial power that eradicates unpleasant odours.
